Aight...Even though This is a quest guide...I'm not going to tell you where exactly
all the land marks are...I'll tell you the general area that they are in...The rest is up to you.
First off if you don't have an orc burger, go kill an orc and pick up the meat that it drops. Then goto a stove or campfire and cook the meat...with luck....You'll get an orc burger. With an orc burger in hand go search for a cave in alon forest, there should be a blind man inside who asks for one in his bio. Give him the burger(by standing in front of him, then click on the burger then the give command.)
The blind man should warp you to a cave with an elf. Kill the elf by either using fireball on it or attacking it with your sword.
After you kill the elf take the herb that it drops. Travel back to alon, then to the bank. One screen down there is a run down castle with a sick man inside.
Give him the herb and you will be teleported to a room....In this room you willl recieve a password.....
If you think you missed the password broadcast password list to make sure you don't have it.
Once you know your password broadcast "the password is(your password here)" without the quotes.
Now At this point I reccomend that you stock up on crystals, get your hp to 64 and say goodbye to all your noob isle friends....you won't be seeing them until they get to mainland.
Head out east of alon to an orange bridge... cross the bridge then use the password command again
Gratz, your on mainland.
